Bug description:
[Impact]
When a BT headset is connected Realtek BT USB controller, HFP profile can't
play or record sound when mSBC codec is used.
[Fix]
At Linux kernel side, add a Realtek specific quirk to support mSBC.
At PulseAudio side, send more data frames until the connected device
sends response.
[Test]
Connect different headsets to the said controller, HFP can play and record
sounds now.
Also verified A2DP profile is unaffected.
[Where problems could occur]
The kernel part is Realtek specific, so the regression risk is very limited.
The pulseaudio side only affects HFP profile, since the codeflow only
changes when a mic is present.
